Making Slag - an overview | ScienceDirect Topics

2010/04/05 · Iron making in the BF produces a slag that amounts to 20–40% of hot metal production. BF slag is considered environmentally unfriendly when fresh because it gives off sulfur dioxide and, in the presence of water, hydrogen sulfide and sulphoric acid are generated. These are at least a nuisance and at worst potentially dangerous.
